This is a list of open source tools and experiments I developed in the last years. There is a main difference between the two categories:
This section include applications, tools and other software that can be used in some way. It is “useful” in the sense that is built with the goal of solving some problem.
This sections contains tests, proof of concepts, weekly programming challenges or personal projects, demos, silly experimentation of mine with new languages and so on. Nothing in this category is strictly “useful”. The only utility in that is to see how I did something and be inspired to do something else. Nevertheless, I think is nice to have them somewhere.
Because I do too many of this stuff, I will list only the one I think are more interesting. For all the rest, use the search box.
